SOURCE: Static lines one screen

as the top is ok and the bottom has this issue.
It looks like the circuit board has a bad connection to your screen.
it is not repairable by you and not an adjustment.
you need to have it repaired.
don't you miss the old wack on the side fix?

SOURCE: vertical lines across my entire screen

My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

SOURCE: samsung tv turning off by itself

I had a similar problem where my 61" Samsung DLP was turning itself off very frequently I had resolved to try replacing the bulb. I called a local TV repair place to see if they had my buld in stock. The guy I spoke to actually told me how to fix my problem! There is a little blue switch behind the bulb access door. The inside of the door has a little piece that presses the switch down. The switch is supposed to work correctly weather the switch is in the up or down position but samsung forgot to take expansion from heat into account. If the switch is held in the upper position by the door and the plastic expands to a certain point, it triggers the set to shut off. This does not occur of the switch is held in the lower position. What you need to do is take the access door off and put it back on by sliding it into position from above. That will hold the switch in the down position, eliminating the problem. My set has not **** itself off ever since.

SOURCE: Lines across screen breaking picture into 4 sections

Based on reported problems with Samsung LCD tvs, It is probably one of three problems:
Separation of layers of the LCD panel;
A defective LVDS cable connection;
A defective T-Con circuit board.
If light hand pressure on the affected area on the LCD panel changes the problem, its the defective panel. If not, manipulating the LVDS cable will reveal the cable defect. If not, coolant spray applied to the T-Con circuit board should reveal if it is defective by temporarily alleviating the problem. Dont remove the back cover if you dont know how to protect yourself from electrical shock hazards. There can be more than 1000 volts in the backlight inverter area.

Vertical jitters on picture - JVC AV48P776


What you are experiancing is loss of High voltage. The line is called a retrace line. It is usally caused by failure of the flyback circuit or aging of the TV tube. This is the single most common failure with CRT based display systems. The high voltage can be tweaked up, to accomidate for the age of the tube. Its a short term solution. Because of the high voltage nature of this circuit, suggest a professional repair.

Vertical color lines


I had the same thing happen to me this morning. I turned on the TV and it had colored vertical lines through the whole screen. I called Sony and they had me unplug the TV for about 15 minutes. This solved the problem. They said the boards just needed to be reset. It fixed the problem and I am happy with my Sony once again.
